Coming in here late but ... the different current ranges have different shunt resistance! The lower ranges have much higher resistances, to get more precise measure of lower current. Amps mode is about 0.1 ohms, mA mode is about 1 or 2 ohms, uA mode is 100+ ohms! so when the external power resistor is 8 ohms, the mA shunt resistance will have a noticeable effect, and the uA shunt resistance will dominate the overall circuit. A good way to test is to put the meter in series with another trusted meter - current will be exactly equal, regardless of different shunt and lead resistances. Great diagnostic and repair of those current frontend diodes, btw, very nice way to recover a great but abused meter.

Great repair, love it. i bought a used Fluke 87V which had this exact same problem and exact same failed components as yours. Replaced both of them and then it is healthy again like a happy puppy on my bench. 😄

This is an example of someone buying a great meter and already destroying the screen by getting it cracked and then damaging the meter itself. Really cute. They are suppose t9 be repairing things with this meter and not repairing g itself.. all the years I have had Mt four flukes they are all still running with never a failure. Love these meters and they get all the care in the world from me in my investments.

Awsome job! Had exactly same issue with a fluke 287 and it was same blown rectifier and diode combo 😁

I did replace the fuse for sometimes, because of wrong connected wires (no warning, if switch is still in current range). Of course, the fuses are expensive, but cheaper than a repairing. After replacement some parts the acccuracy can be reduced, because we have no possibility for re-adjustments.

Great video, thanks. The current reading from the power supply is probably the one that is less accurate. I've had the same issue with Fluke 45 vs cheap PSU.

Don't be cheap ! Buy proper fuses: 440mA / 1000V - amzn.to/3GcjtZw #ad 11A / 1000V - amzn.to/3BUQzuz #ad More info and service manuals can be found here - mobilemodding.info/fluke-87v-amp-ma-ua-range-repair/

Good job. My only negative comment is you don't use enough flux. I even dip the braid in flux alcohol before use; the solder is pulled instantly even from ground planes and the risk to stress the PCB traces is minimal.

Good 🎉 Job

What do I do if my OHM is stuck on 74.9Kohm? My Voltage Ac is off by 6 volts. I have the same one you are fixing.

What would be wrong with a fluke 83 that will not read capacitance? Everything else works great. Thanks John

cool!

Hello, I need a 187FLUKE-187 True rms Multimeter chart, thank you very much, or where can I find it

Nice video, I have a Fluke 289..........I need a Fluke 289 service manual...............Bro Please Link Download for schematic Fluke 289,, thank for advance

buen dia amigo tengo un problema parecido pero ocurre con las medidas de corriente ac y dc tienes algun video sobrr eso

Nice video, I have a fluke 115 f11 flashes on screen like normal, then it shows 4 dashes ?

Where are you getting the schematic. I have a fluke 335 clamp meter that was exposed to high voltage I am trying to fix.

Hi great video👍just a quick question if I may,I have fluke 117,and the beeper is very quiet, can hardly here it now,do you think the buzzer needs replacing or there is something else going on thanks

Hi my friend. I have a question, I see the meter fluctuations while you use the AC settings, is that normal in this meters.? Thanks in advance.👍🏻

Thanks for the video. Are you germanic?

sir i have one fluke179 .that one not working .can you fix for me

Hi. I saw some fluctuations while using the AC settings is that normal in this meters.? Thanks in advance.👍🏻 I’m talking about the first setting in the dial.

Bro Please Link Download for scematic,, thank for advance

15% is a good enough fluke tolerance

it's either dis or dat.
